How can I create a box/cuboid by entering values?
It would be better to set the dimensions of your object, like in the screenshot. This way, you can even make use of blenders ability to use different units. After that, apply the scale of your object. This will normalise the scale while keeping vertices at the right position, and prevents many problems later on, especially if you plan to animate.



There is another way to achieve what you want: At the moment, you added the new object to your scene, there're some parameters to change - see screenshot. Sadly, this is only possible directly after creating the object. Blender creates objects and treats them as meshes directly after, while 3ds Max creates primitives, which can be edited with edit poly later. Both ways have their drawbacks.
